provides the interface connection through which the side impact sensor communicates with the RCM using serial data messages. Acceleration is evaluated by the microchip and transmitted to the restraints control module, which then makes the
decision on whether or not to activate the airbags and pretensioners.
When the ignition is switched on, the RCM supplies power to the impact sensors, which perform a self-test. After satisfactory self tests the impact sensors continually output 'digital acceleration' messages to the restraints control module. If a fault is
detected the relevant impact sensor sends a fault message, instead of the digital acceleration message, to the restraints
control module. The RCM then stores a related fault code and illuminates the airbag warning indicator. Faults can be retrieved by the Jaguar approved diagnostic system from the RCM via the high speed CAN bus connection. www.JagDocs.com
Page 2621 of 3039
Operation of the airbag warning indicator is controlled by a high speed CAN bus message from the RCM to the instrument cluster. The RCM sends the signal to illuminate the airbag warning indicator if a fault is detected, and for approximately 6 seconds during the bulb check at the beginning of each ignition cycle.
Occupant Monitoring
There are two types of occupant monitoring:
In all markets except NAS & Australia, vehicles have an occupant detection sensor
In NAS markets, vehicles have an occupant classification system
For markets which have an occupant detection sensor, this has no interface with the restraints system and only provides the
belt reminder function.
For markets that have an occupant classification system, this provides the RCM with the occupancy status of the front passenger seat. The restraints control module uses this and the seat buckle status in the evaluation of the firing strategy for
the passenger front airbag, side airbag, and pretensioner.
Safety Belt Sensors
The buckle of each front safety belt incorporates a Hall effect sensor that provides a safety belt status signal to the RCM. The RCM broadcasts the status of the two front safety belts on the high speed CAN bus for use by the instrument cluster. In the event of a front impact the RCM will deploy the pretensioners provided the safety belt buckles are fastened. The safety belt buckle pretensioners have a lower deployment threshold than that required by the airbags. Hence it is possible during a minor
collision, which exceeds the deployment threshold and will deploy only the safety belt buckle pretensioners. Airbag Warning Indicator

There is a fault with the passenger airbag firing circuit(s).
The passenger airbag is deactivated with the passenger airbag deactivation switch (where fitted).
Required by passenger seat occupant monitoring (see below).
Passenger Airbag Deactivation Switch (All Except NAS)
The passenger airbag deactivation switch provides a method of manually disabling the passenger airbag. The switch is
installed in the front passenger end of the instrument panel and operated by the ignition key.
When the passenger airbag deactivation switch is operated, it changes a ground connection between two pins in the
connectors of the RCM. When the passenger airbag deactivation switch is selected to OFF, the RCM disables the passenger airbag and, if the front passenger seat is occupied, illuminates the passenger airbag deactivation indicator.
Occupant Detection System
There are two types of occupant monitoring:
In all markets except NAS & Australia, vehicles have an occupant detection sensor
In NAS markets, vehicles have an occupant classification system
For markets which have an occupant detection sensor, this has no interface with the restraints system and only provides the
belt reminder function.
For markets that have an occupant classification system, this provides the RCM with the occupancy status of the front passenger seat. The RCM uses this and the seat buckle status in the evaluation of the firing strategy for the passenger front airbag, side airbag, and pretensioner.
The occupant classification system can determine if the front passenger seat is unoccupied, occupied by a small person, or
occupied by a large person. The occupant classification system consists of:
A pressure pad, installed under the cushion of the front passenger seat, which is connected to a pressure sensor
A safety belt tension sensor, integrated into the anchor point of the front passenger safety belt
An occupant classification module, installed under the front passenger seat.
The pressure pad is a silicone filled bladder. Any load on the pressure pad is detected by the pressure sensor.
The safety belt tension sensor is a strain gauge that measures the load applied by the safety belt anchor to the anchor bolt.
The sensor is located in the lower safety belt anchor point.
